         calendar year 2003. Payments terms are 15% cash-in-advance
         and 85% paid through an irrevocable letter of credit.

         $42 million firm commitments from three state run telephone
         operating companies. Consulting services for these
         commitments commenced in calendar year 2001. These projects
         are expected to be completed in calendar year 2003. Payments
         terms are 50% cash-in-advance and 50% paid through an
         irrevocable letter of credit.

A significant portion of cash-in-advance payments are for consulting services such as initial feasibility studies, network planning, site surveys, engineering etc. During the last twelve months Cyber Digital has provided such consulting services to the three state run telephone operating companies for which it has already incurred expenses and hence, a portion of these payments will be immediately recognized as revenue.
